Abstract EN
Enterococcus faecalis is the most commonly recovered species from failed root canal treatments.
In this study, we tested the capability of a novel intracanal sustained-release filler (SRF) containing cetylpyridinium chloride (CPC) to disinfect dentinal tubules of segmented human tooth specimens.
Human dental root specimens were infected with E.
faecalis V583 for 3 weeks in a static environment.
The tested intracanal medicaments were SRF-CPC and calcium hydroxide (CH).
Each medicament was introduced into the canal of the dental specimen and incubated for 7 days.
The bacteriological samples were taken by shaving the dentine surrounding the root canal with dental burs ranging in size from ISO 014-020.
The obtained dentine powder was collected in test tubes containing phosphate-buffered saline, sonicated, and plated on agar plates.
Colony-forming units were counted after 48 h of incubation.
Random specimens were also examined under confocal laser scanning microscopy and scanning electron microscopy.
A statistical difference was found in the bacterial counts obtained from all layers of infected dentin between the control and the SRF-CPC groups.
CH reduced bacterial viability significantly only in the first layer of the infected dentin, up to 150 μm into the dentinal tubules.
CLSM images showed that SRF-CPC killed most bacteria throughout the infected dentin up to 700 μm of penetration.
SEM images demonstrated the adhesion ability of SRF-CPC to the dentinal wall.
In conclusion, SRF-CPC is a potential intracanal medicament for disinfecting dentinal tubules.
